These Lithium coin cells last longer than their silver oxide counterparts and are built to the highest energizer standards. Their long shelf-life makes them ideal for any compact devices such as remote car starters and keyless entry systems, digital assistants, watches, and back-up power sources to keep clocks and calendars running.

They require extremely infrequent changing yet also power devices you depend on every day, so it's a good idea to keep a spare set around the house in case you notice the juice running low.
